Problems with Lengths

Lesson

Now that we've seen how to convert between units, including when we can convert between units using two steps, we can use these skills to do things like compare lengths. Come and see how we determine who hit the baseball the longest distance, as well as how much fabric you can buy.

The conversion chart can help us as well.

Remember!

When we convert units, we need to remember whether to multiply or divide. Will we end up with more units, that are smaller (multiplication), or will we end up with bigger units, but less of them (division)?
